  • Publication number: 20240406838
    Abstract: A communication apparatus receives status information including a value of a status regarding reception or non-reception of a beacon signal. The status is associated with each of pieces of identification information 25_1 to 25_n. When receiving the status information after transmitting a beacon signal, the communication apparatus selects, based on the status information, another identification information different from identification information of the beacon signal transmitted most recently and transmits a beacon signal including the selected identification information, instead of the beacon signal transmitted most recently.

  • Patent number: 11856927
    Abstract: The present invention has found that chimeric animals suffer from noticeable inflammation after birth, though neither immune response nor inflammation in the fetal period of these animals has been reported hitherto. This is an unexpected finding since chimeric animals in the fetal period were exclusively analyzed in prior studies and thus it is deemed that immunotolerance has been theoretically established therein. The present invention provides a composition for suppressing immune response or inflammation in the fetal period of a born chimeric animal.

  • Publication number: 20220338452
    Abstract: An object of the present invention is to produce a mammalian organ having a complicated cellular composition composed of multiple kinds of cells, such as kidney, pancreas, thymus and hair, in the living body of a non-human animal. The inventors of the present invention applied the chimeric animal assay described above, to a novel solid organ production method. More specifically, the inventors has shown that a model mouse which is deficient of kidney, pancreas, thymus or hair due to the dysfunction of the metanephric mesenchyme that is differentiated into most of an adult kidney, is rescued by blastocyst complementation by the chimeric animal assay, and whereby a kidney, a pancreas, thymus or hair can be newly produced.

  • Publication number: 20220192164
    Abstract: It is revealed that an organ such as pancreas can be regenerated by utilizing a fact that the deficiency of an organ is complemented by injecting an induced pluripotent stem cell (iPS cell) into a developed blastocyst in a blastocyst complementation method. Thus, the present invention has solved the above-described object. This provides a method for producing a target organ, using an iPS cell, in a living body of a non-human mammal having an abnormality associated with a lack of development of the target organ in a development stage, the target organ produced being derived from a different individual mammal that is an individual different from the non-human mammal.

An electron-conducting oxide thin film having a film thickness of 1-100 nm is present between a cathode and an electrolyte comprising the material. The present invention also relates to a method for producing a proton ceramic fuel cell having a hydrogen-permeable film as an anode. The method comprises forming a thin film having a thickness of 1-100 nm between a cathode and an electrolyte comprising BZCY, the thin film comprising an electron-conducting oxide. The present invention provides a novel means for improving the output of a PCFC in which BZCY is used in an electrolyte material, and provides a PCFC having an output that exceeds a benchmark of 0.5 W cm?2 at 500° C.

  • Patent number: 10214193
    Abstract: This hydraulic braking device is provided with: a tubular cylinder; an assisting piston, which is housed in the cylinder so as to be able to move reciprocally, faces a reservoir formed inside the cylinder, and assists a master piston, in a master cylinder, that generates hydraulic pressure for generating a braking force by reciprocally moving from one side to the other as a result of a fluid flowing into the reservoir from a supply source; and a seal member, which is elastically deformable and which seals the reservoir. When the assisting piston is at a location on one side, the reservoir is compartmentalized into a first chamber that communicates with the supply source, and a second chamber that communicates with the first chamber through a restricting flow passage, and the seal member seals the second chamber.
